For any Chern vector \(\gamma =[r,d,\chi )\)  with \(r>0\) , \(d\in {Z}\) , \(\chi \in {Z}\) ,
the condition for \(\mathcal {M}_\infty (\gamma )\ne \emptyset \)  is then [1]}
\(\Delta (\gamma )\ge \delta _{\rm LP}(\mu (\gamma )) \qquad \mbox{or} \quad ( \mu (\gamma ) \in \mathcal {E}\ \mbox{and}\ \Delta (\gamma ) = \Delta _{\mu (\gamma )})\)
